[PATCH 0/3] Allwinner V3s audio codec device tree changes

Here's the Allwinner V3s audio codec device tree changes, which used to
be blocked by the DMA engine code.

The first patch adds the DMA engine device tree node, and the second
adds the codec nodes (digital and analog).

The thrid patch is for Lichee Pi Zero with Dock board to enable the
audio jack and on-board mic.

Icenowy Zheng (3):
  ARM: dts: sun8i: add DMA engine in V3s DTSI
  ARM: dts: sun8i: add audio codec support into V3s DTSI
  ARM: sun8i: v3s: enable audio on Lichee Pi Zero Dock board

Allwinner V3s SoC features an internal audio codec like the one in H3,
and a analog codec like the one in H3/A23 (but much simpler).

Add them in the DTSI file.

The Lichee Pi Zero Dock board has an audio jack and an onboard MIC.

Enable them.

Hi,

You have on extra line here

+		dma: dma-controller@01c02000 {

The leading 0 will generate a DT warning

Since you have that extra line above, you can just drop this new line
here.

Thanks!

This should be the whole size of the memory region.

OK. (Although on the datasheet digital part and analog
part is listed as one region.)
